Near space functioning of the human angular and supramarginal gyri

The posterior parietal cortex (PPC) has been associated with the encoding of events in peripersonal space, but little is known about the precise segregation of parietal areas involved specifically in ‘near‐space’ visuospatial processing. This study applied transcranial magnetic stimulation (TMS) to two parietal areas: the right angular gyrus (ANG) and the right supramarginal gyrus (SMG) in addition to a control site, cortical visual area V5, while subjects performed symmetry judgements on lines presented simultaneously in the left and right visual fields. Eight subjects performed the task with the stimuli presented either in peripersonal or extra personal space. As expected, TMS over the right ANG caused subjects to report lines as being longer ipsilateral to the stimulation site, but only in near space. TMS of the right SMG, however, induced a bias shift in both near and far space, but the change only reached significance in near space. Our findings suggest that, consistent with its role in somatosensory functions, the SMG, like the ANG, is specialised for near space.     

College Atmosphere and Eating Disorders

The authors investigated whether different campus environment factors were related to eating disorder symptomatology at two distinctly different colleges. The first campus was conservative, placing an emphasis on appearance and dress, whereas the second campus was liberal, placing an emphasis on political activism and intellectual talent. As hypothesized, the two schools did not differ in regard to overall levels of eating disorders, yet different factors were associated with eating disorder symptomatology at each school. Implications for eating disorder interventions on college campuses are discussed.     

A respectable job: Factors which influence young Asians' choice of career

To find out why some college or university courses are particularly attractive to ethnic-minority school-leavers, school pupils and first-year students of South Asian (n=158) and UK origin (n = 158) completed a questionnaire relating to occupational choice. The social position attainable from a 'respected' profession and the ability to work with others who share similar beliefs were found to be of greater importance to subjects from an Asian background than to those of UK origin, who placed greater emphasis on personal growth and autonomy. There was no evidence that the Asian young people were consciously choosing careers with the aim of avoiding discrimination.     

Handling from weaning to adulthood does not prevent hyperdefensiveness induced by septal, medial accumbens, or medial hypothalamic lesions

Weanling male hooded rats were handled or not handled for 10 min each day, 5 days/week, for 6 weeks. At the end of this time all animals received one of the following: a septal lesion, a medial accumbens lesion, a medial hypothalamic lesion, or a sham lesion. The animals were tested for defensiveness toward the experimenter on Days 3, 7, and 14 postoperatively. All behavioral testing was done blind. Each of the three lesions increased defensiveness toward the experimenter. However, with each lesion, there was no difference in the defensiveness scores of preoperatively handled and nonhandled animals at any of the postoperative test sessions while those of animals with medial hypothalamic lesions did not. These results are consistent with observations that hyperdefensiveness occurs in human subjects following tumors in each of these brain areas in spite of their familiarity with the situation in which they are observed. They contrast with observations that mouse killing induced by septal lesions is readily prevented by preoperative exposure to a mouse.     

Influence of Item Content and Stereotype Situation on Gender Differences in Mathematical Problem Solving

On standardized tests of mathematical problemsolving, the typical finding has been that women scorelower than men. Experiment 1 manipulated gender labeling(female character, male character, or gender neutral) within the problem question to seewhether this accounted for gender differences inmathematical problem solving. Sixty-four seventh andeighth graders were tested on modified versions of theCanadian Test of Basic Skills (CTBS) with the resultsshowing that although gender labeling affected studentsperformance, it did not account for gender differences.Experiment 2 manipulated both gender labeling and gender stereotype threat for 174 universitystudents writing modified versions of a modelStandardized Achievement Test (SAT). Again, genderlabeling within problem questions did not account forgender differences. However, women scored lower thanmen when they believed that the test had previouslyshown gender differences. There was no gender differencein the performance of the same women and men when they believed that the test was merelycomparing Canadian students with American students. Thissuggests that gender stereotype threat could be a keyfactor in explaining gender differences in mathematical problem solving.     

The psychosocial effects of rheumatoid arthritis on the patient and the well partner

Rheumatoid arthritis (RA) is a chronic disorder that can have a severe impact on patient's lives. This present study investigated four questions regarding the psychosocial effects on patients and their well partners. First we found that depression for both patients and partners were slightly elevated and 35.7% of patients and 23.3% of well partners had scores above the cut-off for possible clinical depression on the Center for Epidemiological Studies Depression Scale. Second, there was no significant difference between the patients' level of distress and that of the partners. Third, there were moderate positive correlations between patients' and partners' scores on measure of psychological functioning. Fourth, there were no differences in either the patients' or partners' well-being based on the gender of the patient. Finally, an exploratory analysis was conducted to examine the factors which influence the patients' and partners' depression and their view of the relationship.     

Similarities and differences between MMPI and MMPI-2 applications to the assessment of posttraumatic stress disorder

The purpose of this study was to address the question: Is the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) comparable to the original MMPI in its applicability to the assessment of posttraumatic stress disorder (PTSD) among Vietnam combat veterans? The question was addressed by administering both the original MMPI and MMPI-2 to 29 subjects classified as meeting Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; DSM-III-R) criteria for PTSD and comparing MMPI and MMPI-2 scores in terms of: degree of association, code-type congruence, diagnostic hit rates (when compared to two other clinical samples, and one normal sample), and congruence of the Keane PTSD Scale (PK). Results reveal highly significant correlations between MMPI and MMPI-2 basic scales for the PTSD sample as well as congruence in 2-point codes comparable to previous studies. The MMPI-2 was found to identify effectively PTSD subjects from the other groups. Results also showed a high degree of association between the MMPI and MMPI-2 in regard to PK scores, although minor differences were found in PK raw scores between the two tests. Overall, the findings suggest a high degree of comparability between the MMPI and MMPI-2 in the assessment of PTSD.
